Multi-tenant SaaS that's built to scale, not rebuilt in six months
SaaS Product Development
SaaS product development is the engineering of multi-tenant software delivered over the web — tenant isolation, subscription billing, role-based access, audit logging and the operational tooling to run it — built to onboard new customers without a new deployment. AI Pinnacle designs and ships production SaaS for the US, UK, EU and Gulf, from MVP to enterprise, with our multi-tenant platform TableOp as proof.
What you get
- Multi-tenant architecture (row-level security or schema-per-tenant, chosen to fit)
- Subscription + metered billing (Stripe), proration and tax handling
- Role-based access control, audit logs, and admin tooling
- Background workers, queues, and real-time features where the product needs them
- Observability from day one (Sentry/Datadog) — not retrofitted
- SOC 2-readiness posture and region-locked data options (EU/UAE)
How much does it cost to build a SaaS product in 2026?
From our last 30+ SaaS builds: an MVP runs USD 28K–55K over 10–14 weeks, a production multi-tenant platform runs USD 70K–140K over 4–6 months, and an enterprise build (SSO, SCIM, region-locked data, event-driven) runs USD 160K–350K over 6–9 months. Anyone quoting a real SaaS MVP in 4 weeks is shipping something you'll rewrite.
What does multi-tenant architecture actually mean?
It means one deployment serves every customer with their data fully isolated, so onboarding a new tenant is a provisioning step, not a new install. We pick the isolation model to fit — row-level security for lean MVPs, schema-per-tenant when isolation and per-tenant customization matter. TableOp runs 500+ venues this way on a single platform.
What kills SaaS builds — and how do you avoid it?
Two things: under-scoping billing (metered + prorated + tax is ~3 weeks on its own) and skipping observability until launch (retrofitting Sentry, Datadog and audit logs later costs roughly 2×). We scope both up front, which is why our fixed-price timelines hold.
Can you add AI features to our SaaS?
Yes — that's a core advantage of building with us. RAG search, AI agents, and LLM features drop into the same platform behind your existing auth and tenancy. See our LLM Integration and AI Agent Development services; TableOp itself ships AI-driven inventory prediction inside the SaaS.

Frequently asked questions
Do you build genuinely multi-tenant SaaS or one instance per client?
Genuinely multi-tenant. Our platform TableOp serves 500+ venues from one deployment with per-tenant isolation. We choose row-level security or schema-per-tenant based on your isolation and customization needs.
How long until we can launch?
A real SaaS MVP ships in 10–14 weeks with 1 PM and 2 engineers. Production multi-tenant platforms take 4–6 months. We deliver a fixed-price scope within 5 business days of discovery.
Can you take over an existing SaaS codebase?
Yes. We audit the current architecture, stabilize billing/observability/tenancy gaps, and extend from there — including adding AI features to a product you already run.
Who owns the code and IP?
You do — 100% of source and IP transfers on final payment, with a 12-month warranty. We sign NDAs before the first architecture call.
What stack do you build on?
React on the front end; Laravel, Node.js, or Django/FastAPI on the back end, PostgreSQL, and your cloud (AWS/Azure/GCP). We pick per project rather than forcing one stack.
